Product description

An autotransformer is a single winding transformer with both primary and secondary windings wound on the same core. The main characteristic of an autotransformer is its voltage transformation capability, or its ability to convert an input voltage into an output voltage while maintaining a specific current level. The maximum input voltage is 400 VAC and the maximum output current is 1,5 A.

Simplifying switchboard mounting, this auto-transformer features robust mounting brackets. It is covered in resin to stop corrosion and lessen noise. Seven voltage taps are available, ranging from 0-130-170-220-260-300-400 VAC. The screw terminal block can be used to connect it.

These autotransformers are used as components in our fan speed controllers, to regulate the speed of fans or pumps, but they can be also used in other applications, such as lighting applications. They are favored in sectors where the voltage control and energy savings are crucial due to their compact design and affordability. Whether they are utilized for motor control, voltage regulation, or lighting applications, autotransformers are essential to maintaining the stability and functionality of electrical systems.

Additional specifications and description

  
What is an autotransformer?
An autotransformer is an electrical transformer with only one winding. It has a single winding with two end terminals and one or more terminals at intermediate tap points. The primary voltage (400 VAC) is applied to the end terminals. The secondary voltage is taken from two terminals, one terminal of which is usually in common with a primary voltage terminal.
  
Typical applications
Autotransformers are integrated in Sentera transformer fan speed controllers. Via two 400 V autotransformers, 3-phase AC fans are controlled in steps by reducing the motor voltage. Autotranformers can also be used in other applications that require a voltage reduction.
  
Superb quality
Sentera has its own production line for autotransformers. We only use the best quality raw materials and we work together with reliable suppliers. To minimise the typical humming noise of transformers, we apply a special impregnated coating. All this guarantees autotransformers of unrivalled quality.
  
Easy to install
This autotransformer can be installed in an electric cabinet. It can be connected via the terminal block with screws. It has an IP20 protection against ingress of dust.
